, A x j as ciaimsf (circa-11s This invention relates a) record punching Inachines and more particularly tothe type in which digit storage devices, either mechanical or electrical in form, are set up by the operator, after which they are utilized'to, control a record punchwill;

ing machine, preferably ot the successive actuationtypeg it A broad object of the present invention is to enable a selective coordination between the col-, umn punching, selecting means and the digit storage devices so that different patterns of cards canbe' punched andto further improvethe system, so that for each form of pattern card punch ing operations'will be automatically efiected and in an eflicient manner without consuming time also results in scarring of punching time by the punching machine as will now be explained.

'In the present system where an amount of say $5.00 is to be set up and considerably more storof the operator that could be employed iorkeying operations. V l

A further object of the-invention is to coordinate a keyboard on which fixed datamay be set up} with a punching machine so that suchdata may commonly be punched one series 01- cards,

Likewise, consistent with the preceding object,

selective connections are interposed between the keyboard and the column selecting means or the punching machine so that the columns of therecord receiving the data maybe selected at Another a predetermined maximum number of'storage 1 columns for'setting up digits of amounts of large denominations and to provide a selective ary a This still further reduction rangement whereby. all of the storage columns may be utilized for storage of amounts of large denominations, or certain storage columns may" be skipped, so .that the operator need onlybe con-' cerned with the setting up of the necessary'stor age columns. 'lhis feature or the invention still further improves the efliciency of the system and renders it moreflexible than heretofore-because in some instances it enables the setting up of storage devices of representations or large amounts and then; when the requirements change, fewer storage columnsneed only be set A l is to provide an arrangement which even eliminates the necessity of setting up some or the stor'. age columns which would ordinarily be set up to represent zeros to. complete digit setting of remaining storage columns.

the operator in setting up the remainingstorcolumns further increases the efllciency of the in time occupied by obiectoifthe invention is to allocate be punched as 005XX, the x punching being dey machine to be operative-after 005 is punched and i age columns are provided to normally enable setting up of digits of amuch higher denomination, it is only necessary for the operator to depress the keys representing the digits 500 which known that it is common practice to punch a field so that the card column at the extreme right receive the digit of units denomination whereas, thecard column at theextreme left receive the digit of the highest denomination. Contrasting with this practice, the present machine,

.through the selective plug connections enables the column selecting means of the punching machine and the storage columns to be interconnected for controlin an inverted manner so that the card column at the extreme left or a fleld receives the digit oithe units denomination; the next column to the right the-digit or the tens denomination, etc. Hence, with such novel interconnections in the present machine for 9, 08,- I

pacity oi five storage columns thecard field will rived 'from the X representing storage column.

The reading out of the first X representation v i from the related storage column will cause the carriage skipping mechanism of the punchin r the card carriage will be skipped from the related still further object of the present invention I the systemand incorporation of this feature column position to the first column or the next field, or to the last column position in the present machine. The variable position of the X storage receiving column enables the card carriage to be skipped from any card column position. thus saving considerable time in punching operations.

It is, therefore, a broad object o! the'invention to provide means under control of an operator to set up in a storage column an X representation;

which is subsequently read out to cause carriage skipping operations.

1 A a result oi the possibility of selective and variable interconnections between the storage, columns and the column selecting means of the punching machine, an alternative arrangement the right, and so on.

operating mechanism enables the card columns to be punched in a manpunched in the same sequence that the digits are set up. Thus, in the modification in-setting up the-digits 500 in the storage columns the card field is punched to represent 500 as before but with the digit 0f the highest denominational order always ap aring in the card column at the extreme left of the card field, the digit of the next lower denomination in the. next column at Upon terminating key Fig. 6 is a representation of a part of the tabulating card punched by a the present machine'p which is known as the Chicago card form.

strokes for digit setup of the storage columns for the amount to be punched, the operator then depresses a'special key which causes X storage in the next storage column, which, upon being read out, causes the punching at the X index point and the skipping of the card carriage from the card column position following that column receiving the punching of the units digit.

Therefore, another object of the invention is to provide means to cause not only the s ping of the card carriage when the storage column representing X is read out, but to also cause the perforation at the X index point position of the related card column. The variable location of this X perforation in cards passing through an accounting machine may be utilized as a control for the purpose of eiiecting a variable column shift so that the amount read from the card field may be shifted to the proper column positions of an accumulator or printing orders of a printing mechanism.

The use of the above features singl and the coordination of the above described features in combination has greatly augmented the efliciency ofv punching systems heretofore employed and in practice has enabled continuous keying operations by the operator without consuming time of the latter due to the time required for completing incidental operations in the punching machine. The reduction of the number or keyingstrokes made by the operator by requiring'the operator to set up only the digits of.- the amoimt without the 0 key strokes for completing a field and the possibility of selectively changing at will the number o'f-card columns comprising a field has increased the overall 'efliciency of the former system.

Otherobjects oi the invention will be pointed out in the following description and claims and illustrated. in the accompanying drawings, which disclose, by way of example, the principle of the invention. and the best mode, which has been contemplated, of applying that principle. I

General description The punching system to be described more in I detail hereinafter consists of a ten key keyboard,

and a card punching machine of the successively actuated type which is controlled by a digit storage unit, all of which units are so 00- ordinated as to enable continuous keying operations by an operator without consuming time of the operator by requiring unnecessary key strokes and'while card ejection and cardieed his operations of the punching machine ensue.

A multiple column keyboard shown herein as having a capacity of seven card columns is provided and in accordance with thekeyboirdietf ting, the digit information represented thereby" is punched by the punching machine to provide common data for a plurality of cards. In the punching""systeiii outlined -hereirigthe variable information to be punched on cards is'tisibly read by the operator from checks and in accord ance with the data printed or written on the checks the operator makes the, desired ten key keyboard operations.

storing columns. The digit setup of the storage the improved'punching maunits is efiected progressively as the keys of the ten key keyboard are-successively-operated; To speed up theoperations of the'machine' and to enable overlap the punching-machine is initiated in operation to'punch a field immediately upon completion-of the digit .setup'in; the related storage columns. 'This makes the storage 001 .'umns'of the storage'unit as they are cleared out.

available for-further digit storage operationsand available before punching machine has completely punched an entitrei card. Overlapping operations eflected in a manner to bede scrilwd more in detail hereinafter greatly reduce the waiting time of the operator if not complete'- 1y eliminating it, enabling the operator to give his or her entire attention to the keying op- Incidentally, the storage unit is controlled by a ten'key keyboard whereas The utility of the present punching system is augmented by making it possible by a rearrangement of circuits topunch either two different card forms outlined in Figs. and 6. The card i'orm shown in Fig. 5 is that required for punched card accounting systems for the New York and Boston Federal Reserve Banks, while the other card form shown in Fig. 6 is that which has been found desirable for the punched card accounting systems of the Chicago Federal Reserve Bank. In the subsequent description, the card form shown in Fig. 5. will be known as the New York form and the other in Fig. 6 as the Chicago" form.

From Fig. 5 it will be observed that the New York form consists of twenty columns of punching, six columns being punched under control oi! the multiple column keyboard and fifteen c011- umns under control of the storage columns.

will be observed that column 6 receives a double punching in that column; one punching under control of the related storage column of the storage unit and the other'punching under control of a bank of keys of the multiple column keyboard.

More specifically, in the New York card form the first two columns are punched under control of the related storage columns to represent the number of the State in which the paying bank is located. Columns 3-0 are punched to represent what is known as the ABA number of the paying bank and this data is punched under control of the related storage columns. Contrasting with the usual procedure of reading out the digits in the storage columns in the order the digits are set up, in the present arrangement the storage devices are read out in reverse order to accomplish punching of the digits beginning with the units order. That is, the units, tens, hundreds and thous'andths digits are punched in columns 3-6 successively. This method, or arrangement of punching, facilitates sorting operations effected under control of such columns of the card. Columns 6-H of the New York card form are punched under control of the multiple column keyboard and represent the ABA numberand state number of the sending punchingaccording to the New York card form, making it unnecessary for the operator to punch the first four zeros in cases where the amount on the check consists of five figures or less.

When, for example, a check of an amount of $5.00 is to be punched and'which amount, denominationally speaking, is small compared to the maximum denominational capacity of nine columns of the amount field, the storage columns are delimited to five storage columns I I, l2, l3. I4 and l5,and storage columns I, 8, 9 and ID are skipped. The 0 key is depressed to set up X representations in storage columns II, I! and then the digit keys are successively depressed to set up 500 in storage columns l3, l4 and I5, respectively. The storage columns are read out reversely to punch card columns l2, l3 and M to represent 005 under control of storage columns l5, ll, 83, respectively, When the X representation of storage column I2 is read out by the column selector in the punching machine effected when the carriage is in position to punch card column l5 (see Fig. 5) this X readout will set in operation a skip mechanism which will skip the card carriage from the column i5 position to the last card column position and then eject the card. This enables a great saving in time of operation of the punching machine. In other instances where the check amount is $1,000, or more, the operatormay first depress the X key on the ten key keyboard which expands the storage columns to its full capacity of nine columns of amount. r

. The Chicago card form shown in' Fig. 6 in card fields is arranged in a slightly different manner from the New York card form and consists of thirteen card columns but the same basic data. is punched on the card. TheChicago card form consists of column I which is punched under control of the keyboard to represent the number of the State of the paying bank. Columns 2-5 are punched to represent the "ABA number of the paying bank and are punched under control of the related storage columns. As in the case of the New York card form, re-

' verse punching ensues for columns 2, 3, I and 5.

national order. The units digidof the number appears in column I! and the highest denominational digit appears in column 20 with other digits in between such columns. In this case,

' however; the reverse denominational order of digit punching has been adopted because it permits a saving of punching time andtimeoi the operation of the punching machine by making it possible to skip over higher numbered columns of the card which-are not punched because the amount of the check is small.

Due to the relatively large size of the check necessary for the operator to punch a great many superfluous zeros to the left of the significant amount field on the New York form, it will be Columns 5-1 of the Chicago form are punched under control of the multiple column keyboard to represent the batch number which remains -constant for a series of cards. It will be observed that column 5 receives a double punching; one under control of the related storage column and the other under control of the multiple column keyboard. Finally, columns 8 to l3 are used for the allocation of the digit punching of the amount of the check. On the Chicago form the check amount field consists of only six columns and no skipping circuit has been provided to eliminate part of the storage columns.

- However, since the amounts on the checks are usually small, provision has been made for a different method of punching the amount of the check for the Chicago card form, but this is applicable for the New York card form as well by changing the plug interconnection between storage columns and the column selector. Instead of punching the check amounts in reverse denominational order 'as described for the New York card form and still provide an X skipping over 'the remaining columns, it is possible to utilize another procedure in which the check amounts are punched in normal denominational order beginning with the left hand column of the amount field. Thus, in setting up the storage columns for an amount of $5.00, the operator wfll merely depress the keys of the ten key keyboard for the number 500 to set this number in the storage columns and then depress the manual bar to signify completion of the operation which will also set up an X representation. This amount 500 would be then punched in direct order on the card as 500 in columns I2, I3, I4 for New York form and columns 8, 9, I for Chicago form and a perforation would be punched in the X index point position of the column following the last of the above mentioned zeros. With this X perforation in column I of the New York form, or column II of the Chicago form, it can then be utilized as a control in a conventional tabulating machine to control shifting circuits to shift the 500 to the right a sufilcient number of places to bring the digits of the number into the corresponding orders of the accumulator or type bars. This method of punching the amount will be referred to in a later discussion as zero elimination.

The sensing of the X representation will, as before, cause the carriage skipping mechanism to be operative at different column positions to skip over the higher numbered card columns at the left of digit punching of the amount field.

Keyboard left as viewed in Fig. 3. Each of the sliders cooperates at its left end with a bail- I2I to rock the same counterclockwise and the bail in turn will rock a lever I22 to close a pair of contacts I23. Contacts I23 are-the bail contacts and are common to the numeral keys "TN and are closed upon the depressionof any of said keys.

Individual contacts I24 of whichthere is one for each key IIIN are also closed by the depressi-on of a key. For each slider there is also a lever I25 which is rocked to close the associated pair of contacts I24.

The special key II'IX operates a similar slider I20 and lever I25 to close a pair of contacts I24X shown in Fig. in. Also for the key II'IE there is a separate slider and lever I25 which will close a pair of contacts I24-E (Fig.1a). The manual bar M8 when depressed also like key IIIE closes a pair of contacts not shown in Fig. 3 but desi nated in Fig. 1a as contacts I30. Neither of the keys I X, I E or the manual bar I I8 closes the bail contacts I23. These keys and their contacts are mechanically independent of the remainder of the mechanism and being mounted in aseparatekeyboardK (Fig. 12) may be located in relation to the remainder of the apparatus for convenient manual operation. I

In starting, the first key depression causes a circuit to be closed from the current supply line I05, through the bail contacts 923 (Fig. 1a),

through FI-2, F2-2 contacts, wire 506, through relay contacts 'IRI (Fig. 17') now in the position shown, cz-c contacts, relay coil Ct, to ground.

Accordingly, relay contacts CI--I6 close to provide a stick circuit back to the line 505 through relay contacts F2--2 and FI2 and hail contacts 523 (Fig. 1a). Relay CI (Fig. opens contacts (35-9 and closes contacts CI-I0. The closure of the latter closes a circuit from wire II'IN, an error key 'IIIE,'

- circuit extends through contacts PR4, TDI,

I06 through contacts (Ii-l0 to relay coil IR to is as relay coil TB is and remains energized by reason of its stick contacts TR4, which stick R3-I, ERI, and wire I01 back to line I00. Hence, when the bail contacts open upon the re-' lease of the pressure on the depressed key, relay CI deenergizes but relay TR. remains energized. Upon the next key depression, the circuit extends from the line I05 through relay. contacts TRI now shifted (Fig. 1a), ;CI--9 now closed, to grounded relay coil C2, the stick contacts C2-I0 providing a stick circuit back to line I00 through FI-2, F2-2 contacts, and bail contacts I20. Relay coil C2 closes its contacts C2-I0 to energize grounded relay coil TD which opens its contacts 'I'DI to break the stick circuit of the relay coil TR, which deenergizes. The return of relay contacts TRI to normal does not causerelay coil CI to energize because of the opening of relay contacts 02-0. It is thus seen that on odd key depressions relay coil Cl energizes while upon" The individual contacts I24 are closed by the respective numeral keys II IN and a circuit is extended from line I05 throughFI-i', F2-2contacts, to the contacts I24 of the 5, 6, 7, 8, 9 and 0 digit keys, whereas upon the depression of one of the digit keys 1, 2, 3, and 4 .the circuit extends from the bail contact I23 through the COMI contacts now closed, FI3 and F2-3 contacts, to

contacts I 24 of the digit keys 1-4. When the bail contacts I 23 close, a circuit-is closed from such contacts to the grounded COM relay coil which closes the contacts COMI toextend the impulslng circuit to the I24 contacts related to digit keys 14'. From the other side of the contacts I24 closed by the digit keys 1-.9 there are respective wire connections to grounded relay coils KI-K0,

-one relay for each key, so that depression of a key will energize its respective K relay and close respective 1! and 2" contacts if such relay coil is provided with such contacts. For example, the digit keys designated 1, 2, 3 and 4 upon the closure of their respective contacts, energize only their related relays KI-K4. However, for the 59 digit keys which energize their related KI-K0 relays, the latter also close additional "1 and "2" contacts so as to cause in addition the selective energization of the relays KI-K4. Such circuit arrangement provides for the energization of the K relays singly or in combination according to the following code: 1
